Structure can control the inner diameter size that the diameter changing mechanism changes the first runner.Wherein, control mechanism can control to variable diameter
The size of current or voltage swing of mechanism input or the size in magnetic field, so that the size of diameter changing mechanism is controlled, certainly, control
Mechanism can also control the inner diameter size of diameter changing mechanism by transmission information command.In view of diameter changing mechanism realizes the side of variable diameter
It is a variety of no matter formula exists from the form of structure or structure combination software, and present embodiment is not intended to be limited in any herein.
Specifically, the diameter changing mechanism can be the variable diameter solenoid valve 304 being set on the wall of the first runner.Power supply
Cable 107 and signal-transmitting cable 206 connect electromagnetism Diameter changeable valve 304.
Wherein, the variable diameter solenoid valve 304 includes multiple electromagnetism variable diameter valve blocks 3041 circumferentially arranged, for example electromagnetism becomes
Diameter valve block 3041 can be 2-10 block.Pressure spring 305 is equipped between the two neighboring electromagnetism variable diameter valve block.The control mechanism passes through
It is separate or close to control the two neighboring electromagnetism variable diameter valve block 3041, to change multiple 3041 institutes of electromagnetism variable diameter valve block
Surround the size of circumference.
Specifically, two neighboring electromagnetism variable diameter valve block 3041 can be carried out by magnetic field caused by electromagnetic induction attract or
Repel, correspondingly, control mechanism can control the size of current inputted to electromagnetism variable diameter valve block 3041, to control each electromagnetism
The size in magnetic field produced by variable diameter valve block 3041.
In the present embodiment, for the structure of electromagnetism Diameter changeable valve 304 as shown in Fig. 3 A, Fig. 3 B, electromagnetism Diameter changeable valve 304 includes pressure
Spring 305 and electromagnetism variable diameter valve block 3041.Fig. 3 A be 304 original state of electromagnetism Diameter changeable valve (it can be appreciated that non-undergauge state,
Electromagnetism Diameter changeable valve 304 can be not powered under this state, that is, control mechanism will be between power supply mechanism and electromagnetism Diameter changeable valve 304
Truncation), electromagnetism variable diameter valve block 3041 is in open configuration under the active force of pressure spring 305, at this point, fast 3041 groups of electromagnetism Diameter changeable valve
At the flowing hole of a circular hole, this flowing hole can be consistent or identical with the inner via hole diameter of damping dummy piston 302.
Specifically such as Fig. 4 A to Fig. 6 B, the wall of the first runner is equipped with the circumference for accommodating the variable diameter solenoid valve 304
Groove；The internal diameter of the first runner is constant along its length when the 304 non-variable diameter of variable diameter solenoid valve.In present embodiment
In, the quantity of the variable diameter solenoid valve 304 can be multiple (two or more).Multiple variable diameter solenoid valves 304 are along described
The extending direction of outer tube is arranged.Wherein, the quantity of circumferential groove is identical as the quantity of variable diameter solenoid valve 304 and corresponds.Phase
It can be spaced a distance between adjacent two variable diameter solenoid valves 304, to play preferably damping effect.
In the present embodiment, Fig. 3 B is the state after electromagnetism Diameter changeable valve 304 starts, and electromagnetism variable diameter valve block 3041 encloses composition
One circular closure channel, close passage diameter are less than the first runner internal diameter of damping dummy piston 302.Due to first runner
Internal diameter becomes smaller, and therefore, the upper end area of damping dummy piston 302 increases, and drilling fluid acts on the production of damping dummy piston 302 thus
A raw bigger down force.
It in the present embodiment, is the inactive stress of electromagnetism Diameter changeable valve 304 of damping dummy piston shown in Fig. 4 A and Fig. 4 B
Figure.As shown in Figure 4 A, 302 upper surface of damping dummy piston is Pp by pressure in drilling tool, and upper surface area is Auo, variable diameter step
By annular pressure Pa, variable diameter step surface area is Ado in face.
Fig. 4 B is 302 stress condition of damping dummy piston, by downward directed force F o, upward directed force F a, to realize essence
Really control considers the drilling fluid in drilling tool shock absorbing tool to the active force WOB of 302 lower end surface of damping dummy piston together.To,
Relationship is as follows between these power:
Fo=Auo×Pp
Fa=Ado×Pa
WOB+Fa> Fo
At this point, the suffered resultant force of damping dummy piston 302 is upwards, therefore, as shown in Figure 6A, damping dummy piston 302 is in
Upper dead center position (upper dead center position outer tube inner wall be equipped with position-limiting action variable diameter at).
It is force diagram after damping dummy piston electromagnetism Diameter changeable valve starts shown in Fig. 5 A and Fig. 5 B.Shown in Fig. 5 A, damping balance
302 upper surface of piston is Pp by pressure in drilling tool, and upper surface area is Aso, and variable diameter step surface is by annular pressure Pa, lower end surface face
Product is Ado.
Comparison diagram 4A and Fig. 5 A, 302 upper surface of damping dummy piston due to electromagnetism Diameter changeable valve 304 start and area becomes larger.
Fig. 5 B is 302 stress condition of damping dummy piston, by upper and lower effect Fs, upward directed force F a, considers drilling tool damping work together
The active force WOB of drilling fluid in tool to 302 lower end surface of damping dummy piston.Relationship is as follows between these power:
Fs=Aus×Pp
Fa=Ado×Pa
Fs> WOB+Fa
At this point, the suffered resultant force of damping dummy piston 302 is downwards, therefore, as shown in Figure 6B, damping dummy piston 302 is in
Lower dead point position.Under normal conditions, the downward resultant force of damping dummy piston 302 is greater than upward resultant force 20-30KN at this time.
In this case, when drill bit is beated, drill bit drives the flat piston 302 of damping upwards by lower contact 308
Movement, then under hydrodynamic thrust effect, damping dummy piston 302 is moved downwardly to bottom dead centre (Fig. 6 B) again.It is pushed away in fluid power
Under dynamic, drilling tool, drill bit axial vibrations mitigated significantly by the effect of this hydraulic resistance balance, to protect drilling tool, drill bit, improve
Drill bit efficiency of breaking rock, extends drill tool life.
The upper surface of damping dummy piston 302 is different after different electromagnetism Diameter changeable valves 304 starts, therefore provides damping intensity
Range is not also identical, it is generally the case that 304 quantity of electromagnetism Diameter changeable valve is 1-10 in damping execution system.
In conclusion the shock absorbing tool that present embodiments provide for a kind of suitable for reducing drilling tool axial vibrations, the damping
Tool can carry out real-time data acquisition to underground axial vibration, analysis is handled and control, be that one kind can carry out closed loop in underground
The axial damping tool of control.
The drilling tool shock absorbing tool relies on the underground axial vibration of vibration survey sensor real-time measurement, and damping processor is according to setting
Determine program according to preset frequency collection analysis axial vibration data, it is big according to oscillation intensity when axial vibration is more than setting value
Different electromagnetism Diameter changeable valves, makes damping executing agency be in damping working state in small starting damping execution system.Damping executes
Mechanism mitigates drilling tool, drill vibration by hydraulic resistance balance significantly, improves the bit drilling tool service life, improves drill bit efficiency of breaking rock.
In addition, present embodiment provide shock absorbing tool again when axial vibration be no more than setting value when, do not start electromagnetism change
Diameter valve.To which the drilling tool shock absorbing tool of present embodiment can start damping executing agency in real time, improve drill bit efficiency, also can
It does not work in the case where underground vibrating does not influence drillng operation, to extend the axial shock absorbing tool service life.
